You may have notice that when you completed the jailbreak process and you open up your iOS device to the home screen, there may be a few stock apps that are replaced with a white background and grey lines. You can still open up the apps and they still function correctly, but if you want the normal app icons back, follow these steps:

1. Plug in your ALREADY JAILBROKEN iOS device into the same computer you originally jailbroke with2. Open the evasi0n 7 tool and start the jailbreak process again3. When you get to the part where it asks you to unlock your iOS device and click the evasi0n app, click the evasi0n app, then quickly hold the evasi0n app, then delete it4. Quit out of the evasi0n tool on your computer and unplug your iOS device

If the app icons are still blank, reboot your iOS device and see if that works
